Here is problem solution in Python, Java, C++, C and Javascript - https://programmingoneonone.com/hackerrank-counting-valleys-problem-solution.html

This is my javascript solution, cheers!

let countUpDown: number = 0; let countValley: number = 0;

for( let step of path ){
    step === "U" ? countUpDown += 1 : countUpDown -= 1;

    if( countUpDown === 0 ){
        if( step === "U" ){
            countValley += 1;
        }
    } 
}
return countValley;

Can you help me to solve the interesting algorithm on my website Insta Pro APK?

def countingValleys(steps, path): elevation = 0 valleys = 0

for step in path:
    if step == "D":
        elevation -= 1

    elif step == "U":
        elevation += 1
        if elevation == 0:
            valleys += 1

return valleys
